Description
BACKGROUND OF THE INVENTION
[0001] 1. FIELD OF THE INVENTION
[0002] This invention relates to a spring belt chair rest part, and
is especially related to a chair rest with an elastic back made of
radially tensioned elastic belts.
[0003] 2. DESCRIPTION OF THE PRIOR ART
[0004] Elastic chair rests have become popular in recent years
because of their simple structure and their unique shape. They are
often used as leisure chairs. CN203000054U has introduced an
elastic rope chair rest part, the main body of which consists of a
surrounding frame and a backed seat. The backed seat further
consists of a seat and a back. The back is made of crossed elastic
ropes, and the rest part is tensioned into a planar structure when
there is no load on it. The chair rest part was novel and unique
shape, and it was reformed from the previous oxford cloth rest part
in the past, and the user will feel funny and resilience. The
elastic rope diameter is small, and hips may be sharply/painfully
pressed into the ropes. The ropes also have to be weaved in a
complicated way. Therefore, manufacturers are searching for a new
method to improve the traditional elastic rope chair, which becomes
a target for this invention.
[0005] None of the above inventions and patents, taken either
singly or in combination, is seen to describe the instant invention
as claimed.
SUMMARY OF THE INVENTION
[0006] This invention shows in at least one embodiment a backed
seat for a chair rest part which is woven by elastic belts.
[0007] This invention is realized by an elastic belt chair rest
part consisting of a surrounding frame and a seat having a back
("backed seat"). The backed seat consists of a seat and a back. The
seat is made of the same material as the surrounding. It is
characterized in that the back is weaved by tensioned elastic
belts, and the two belts ends are respectively fixed to the
surrounding frame and seat.
[0008] The surrounding frame is a circle, the seat back side is a
circular edge, and one end of elastic belt is radially fixed to the
circular edge.
[0009] The surrounding frame is a circle. The seat back side is a
circular edge. One end of the elastic belt is fixed to the circular
edge. The multiple elastic belts are uniformly distributed and are
parallel.
[0010] The elastic belts are uniformly arranged and are fixed to
the circular edge of the seat at one end, and the point at which
the belts would cross, if extended is on the central line of the
chair rest part. That is, the belts "fan out" from a central line
of the chair rest.
[0011] In a further embodiment, the radial elastic belts are
divided into two groups. Intersection ("cross") points of the
extending lines from the two groups are distributed at both sides
of the chair rest part central line. That is, one set of belts
points to one side of the chair rest, and the other set of belts
points to another side of the chair rest. The two groups of belts
are overlapped with each other, over and under.
[0012] The upper part of the back is tensioned by a Z shaped
elastic rope. The two rope ends are separately fixed to the
surrounding frame, and the elastic rope is at the back of elastic
belts.
[0013] The surrounding frame is preferably a circle or a square
with an inner circle.
[0014] This invention inherits the funny and elastic structure, and
further brings a novel and unique shape to provide a more
substantial and comfortable fit and feel. This is especially true
when the seat is made of common fabric, where the sitter will feel
no deformation of the material and the hips will not thus be
tensioned or pressed, and the back can be strongly supported by the
elastic belts weaved in a Z shape. Moreover, the people's demand
for a more diversified lifestyle can be satisfied by colorful and
foldable elastic belts and with the surrounding frames in differing
colors.
[0015] These and other objects of the present invention will be
readily apparent upon review of the following detailed description
of the invention and the accompanying drawings. These objects of
the present invention are not exhaustive and are not to be
construed as limiting the scope of the claimed invention. Further,
it must be understood that no one embodiment of the present

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
[0031] The circular foldable chair in FIG. 1 and FIG. 2 consists of
a foldable support 1 and the chair rest part 2. The foldable
support 1 contains a support 11 suspending or fixing the chair rest
part 2. In this preferred embodiment, the support 11 is a circle.
The chair rest part contains a surrounding frame 1 and a backed
seat on the support 11. The backed seat contains a seat 22 and a
back 23. The seat 22 is made of the same material for the
surrounding frame 21, such as oxford cloth. The back 23 is weaved
by a tensioned elastic belt 24. The two ends of the elastic belt 24
are respectively fixed to the surrounding frame 21 and the seat
22.
[0032] In the figure, the surrounding frame 21 is a circle with an
inner circle and an outer circle. The seat 22 has a circular edge
at the side towards the back 23. The elastic belt 24 is radially
weaved to the circular edge of the seat 22. More particularly,
elastic belts 24 are uniformly arranged and fixed to the circular
edge of seat 22 at one end, and the crossing ("intersection") point
of the belts 24, if extended, is at the central line on the chair
rest part 2, i.e., they are integrally symmetrical at both sides of
the chair rest part central line and fan out symmetrically.
[0033] In FIG. 2, a Z shaped elastic rope 25 is tensioned at the
back 23 to reinforce the supporting strength of the upper part of
the back 23. The two ends of the elastic rope 25 are separately
fixed to the surrounding frame 21. The elastic rope 25 is at the
back of ("behind") the elastic belt 24 to improve the supporting
force of the upper part, and the symmetrical chair rest part is
provided with a varying shape.
[0034] In FIG. 3, the chair rest part 2 can be made by overlapped,
radial elastic belts 24. The radial elastic belts 24 are divided
into two groups, where the crossing points of extended lines from
the two groups of elastic belts 24 are distributed at both sides of
the chair rest part 2 central line. That is one set of belts points
to one side of the chair rest, and the other set of belts points to
the other side of the chair. The two groups of belts 24 are
overlapped with each other up and down ("over and under").
[0035] In FIG. 4, the surrounding 21 is a square shape with an
inner circle matched to a foldable chair with a square chair rest
part. The seat 22 has a circular edge at the side towards the back
23. One end of the elastic belt 24 is woven to the circular edge of
the seat 22. Multiple elastic belts 24 are uniformly distributed in
parallel. And to improve the stiff symmetrical shape, a Z-shaped
elastic rope 25 is tensioned to the upper part of the back 23 to
reinforce the back support and beautify the shape.
[0036] In all, the figures introduce three different chair rest
parts. And especially the weaved structure of elastic belt 24 is
applicable for both a circular chair rest part and for a square
chair rest part. The "weave" mentioned in this invention has two
meanings, one is that multiple elastic belts are set between the
seat and the surrounding frame into a back; and the other is that
multiple elastic belts are woven in a designed pattern, and
overlapped up and down ("over and under") into a back. Furthermore,
the elastic belts are tensioned, but not excessively tensioned, so
that it provides an elastic deformation under sitting loads. The
"radial" mentioned is similar with "radialized."
[0037] While this invention has been described as having a
preferred design, it is understood that it is capable of further
modifications, uses and/or adaptations of the invention following
in general the principle of the invention and including such
departures from the present disclosure as come within the known or
customary practice in the art to which the invention pertains and
as maybe applied to the central features hereinbefore set forth,
and fall within the scope of the invention and the limits of the
appended claims. It is therefore to be understood that the present
invention is not limited to the sole embodiment described above,
but encompasses any and all embodiments within the scope of the
following claims.
